Isthmiophora melis (Schrank, 1788) Lühe, 1909
This is a trematode, along with Euparyphiumbeaveri and Echinostomamelis make up a group that is mainly a parasite of otters and badgers that on rare occasions find their way into dogs. It seems that it is also possible that this trematode could be found in cats. The life cycle, like that of Artyfechinostoma appears to involve infection via the ingestion of frogs which is how cats are likely to be infected.
